HORSESHOE-MACHINE.

SIJECIFICATION forming pari'. of Letters Patent No. 331,623, dated December 1, 1885.

Application tiled April 23, 1884. Serial. No. 128,900. (No model To @ZZ whom it 11mg/ concern,.-

Be'it known that I, Devin J. FARMER, of Penn Yan.y in the county of Yates, in the State of New York, have invented new and useful Improvements in Horseshoe-Machines, of which the following, taken in connect-ion with the accompanying drawings, is a full, clear, and exact description.

This invention relates to a machine designed :o to manufacture horseshoes and mule-shoes complete from the bar, and has more particularly reference to the machine for which Letters Patent No. 243,536 were granted toD. J. Farmer and S. Farmer on the 28th day of June,

The object of this invention is to make said machine more durable and more eflcient in its operation; and to that end the invention consists in the improved construction and 2o combination of the constituent parts of the machine, as hereinafter fully described, and set forth in the claims.

In the annexed drawings, Figure l is a plan view of my improved horseshoe-machine and its feed mechanism. Fig. 2 is an end View of the same, the mechanism which actuates the shoe-bending rollers being omitted to better illustrate some of the important features of my invention. Figs. 3 and 4 are vertical secgo tions taken respectively on lines x a: and y y, Fig. 2. Fig. 5 is an elevation taken at the side of the machine, showing the. connection of the main shaft with the oscillating shaft of the arm which carries the die and former for bending the shoe.

Similarletters of reference indicate corresponding parts. 7c

A represents the supporting-frame of the machine. It consists, essentially, of a stout bed or base from which rise two rigid walls.

In suitable bearings on said walls are'mounted the rotary main shaft B and a rock-shaft, F, extended across the frame, the main shaft being provided on one of its 'ends with a crank-wheel, G, which is connected by a rod,

H, with an arm, I, on the rock-shaft,and thus transmits the requisite motion to the latter. 8O To the rock-shaft is attached the oscillatory arm K, which carries on its free end the die L and former M,around which the horseshoeblank is bent in the manner hereinafter explained, said former being seated in a longitudiual cavity in the die and backed by a spring which yieldingly holds the former to protrude at the face of the arm K in the usual and well-known manner and not necessary to be here illustrated.

Across the path of the oscillatory arm K, and nearly or quite in range with the face thereof, is a channel, a', formed bya plate, b, extended across the upper part of the frame A, and by a rabbeted plate, b', secured to the' 95A top of the plate b, the upper plate having a notch, c, to allow the former M to pass through it in the oscillation of the arm K. Thelower plate has an excision, c', of such a length as to compel the bar introduced4 in the channel c" roo to be bent part way around the former M in its passage through said excision. The bending ofthe aforesaid bar is completed by the same mechanism as described and shown in the patent ofD. J. Farmer and S. Farmer, No. 243,536, hereinbefore referred to, said mechanism consisting of rollers 8 8, mounted on horizontal slides 9 9,which are arranged at opposite sides of the path of the former M, and are moved toward and from the same by levers 10 10, the outer ends of which are drawn together by a spring to retract the rollers,v and are forced apart by a wedge, 11, on the end of an arm, 12, fastened to a shaft, 13, and turned by a cam, 14, on the main shaft, acting on an arm, 15, onthe shaft 13 at the proper period, and to the necessary extent to cause the rollers 8 8 to be forcibly pressed against the partiallybent blank, and by following around the outer edge thereof and forcing it against the former to complete the bending of the blank as it is carried down between said rollers by the former.

Before the baris subjected to the aforesaid bending process it is subjected to a swaging and creasing process by the following instrumentalities: On the end of the plate b, at the feed side of the machine, is arranged an adjust-able creaser, C, consisting of a horizon-tal plate presenting a beveled edge toward the feed-passage or guide-groove a of the ma; chine,which plate rests in a holder or sustaining-shoe, f, having tlangesf extended around three sides thereof, and overhanging the top to embrace the creaser C, and a co\ er, f2, placed upon the creaser, as shown in Fig. 8 of the drawings. The holder-f rests with its front portion on an elevation near the edge of the plate b, forming a rocker-bearing for the holder f. The rear portion of the said holder is supported by set-screws e e, extended vertically through the holder, and bearing with their lower protruding ends on the plate b. The set-screws work in screw-threaded eyes in the holder, and by turning them the rear portion of the holder f is raised or lowered, as may be required to bring the creaser C in properposition over the guide-groove a to crease thebar t from which the shoe is to be formed.

By means of a dog, h, removably attached at one end to either the frame A or a portion of the plate b back of the holder f, and bearing with its opposite end or free end on top of the cover f2, the creaser is rmly held in its sustaining-shoe f, and the latter is confined to its bearings on the plate b.

Opposite the creaser C and facing the same is a slide, S, mounted on the wall of the frame A, which slide carries a plate, E, provided with agroovedoverhangingportion,the groove a of which constitutes the feed-passage wherein to pass to the machine the bar from which the shoe is to be formed. Said groove a is adapted to be brought in range with the channel a', hereinbefore described, so that an uninterrupted passage to the oscillatory former is obtained.

On the plate E is hinged the presser D, the free end of which is provided with an overhanging face, D', occupying the side of the groove a opposite the creaser C and serving to press against the latter the bar to be creased preparatory to bending it into shoe shape, as hereinafter described.

The object of hinging the presser is Ato ren.- der it readily removable from the groove a whenever it becomes necessary for the operator to obtain access to said groove or in case the bar is to be fed to the machine without creasing the bar. The position ofthe presser when removed as aforesaid is illustrated by dotted lines in Fig. 9 of the drawings.

In order to admit of repairing or renewing the face D of the presser when required, I fasten said face on the hinged part D by removable bolts or other suitable detachable fastenings, which allow the face D' to be removed from said part D. The Slide S, with its aforesaid appurtenances, receives a quick reciprocating motion by means of vertical levers P P, pivoted on opposite sides of the frame A by the rock-shaft passing loosely through them. Said levers are provided above their fulcrums with sockets, in which rest the ends of push-bars or knuckles lc 7c, which are pivoted at their opposite ends on the slide S, and serve to. push said slide toward the creaser by the movement of the leversP P in one direction.

The slide S is retracted during the movement of the levers in the opposite direction by the following instrumentalities: Horizontally through a socket in the back of the slide S passes a rod, Z, which is provided with a head in said socket, and between the head of the rod and end of the socket is interposed a spiral spring, m. The opposite end of the `rod Z is screw-threaded and screwed into a 1 socket in the wall of the frame A, rising be- IOO tween the levers P P, as -illustrated in Figs. 1

and 9of the drawings. The spring m becomes compressed by the movement of the slide S toward the creaser, and the rrsistance of said spring serves to retract the slide so soon as the l-atter is relieved of the pressure transmitted to it by the knuckles la k in the man` i ner before stated.

To. the main shaft B are attached cams Q Q,l having an eccentric contour terminating abruptly, as at g, Fig. 4 of the drawings. These cams engage the lower end of the levers P P, and impart a quick and positive oscillatory movement to the same. Back of the lower ends of the two levers are elbow-levers R R, one arm of each of which rests on a stout spring, a, and the other arms are connected Withthe lever P by push-bars a a. These elbow-levers serve to quickly throw the lower ends of the levers P P forward after the release of the` latter from the cam Q. The described move-c.

ment is essential in order to accelerate the. creasing process, and thus prevent as much as. possible the heating of the creaser C, which. heating is one of the defects of the machineY covered by Letters Patent No. 243,536, hereinbefore referred to. Over the creaser G is a..l u*

rockshaft,T, mounted on portions oi theframe A, rising above the creaser, and from said rock-shaft project two rmly-attached jaws, T T', from which is suspended the swage-carrying arm U, the connection of said arm wit the jaws T being such as to allow the said arm to swing and follow the slideS inits movement, and thus maintain its hold on the shoeblank while subjected to the action of the creaser, as illustrated in Fig. 7 of the drawings. The swageU is secured to the arm U in such a manner as to allow it to be detached for repairs or renewal, or for exchanging it with other swage-irons of different forms and dimensions, as may be required for the different sizes of shoes to be formed. The swage-iron normally stands directly over the feed-passage c, and receives a downward pressure by a lever,V, fastened to the end or" the rock-shaft, and having its free end lying against and actuated by a cam, V', secured to the main shaft B. The cams Q and V are arranged in such relation to each other as to synchronously actuate the slide S and rock-shaft T. The bar from which the shoe is to be formed being introduced in the groove or feed-channel a, and brought in proper position between the creaser C and slide S, is pressed against the creaser by the presserD D on the slide S, and simultaneously receives the impact of the swage U', the pressure of which latter resists the vertical distention of the bar incident to the action of the creaser, and at the same time imparts to the bar the contour illustrated in Fig. 11 of-the drawings, whereby the ends of the bar receive a lateral distention, which produces the requisite increased thickness at the heels of the shoe. After the aforesaid creasing and swagingfl has been effected, the slide S, with its presser D D", and the swage U recede immediately from the bar. In the latter movement the slide S draws the bar away from the creaser by t-he so-called strippers o and o connected 'respectively to the inner end of the slide and to the outer end of the portion of the plate E, which is provided with the'groove or iced-passage a. Said strippers engage the edge of the` heated bar adjacent to the creaser, and in addition to their aforesaid function also serve to guide one side of -the bar in its movement on the feed-passage.

The form and operation of the inner stripper are illustrated in a separate view under Fig. 6 of the drawings.

In order to preserve the plateZE, I apply to the part thereof which contains the feed-passage a a steel lining, a2, tted removably in a dovetail countersink in the passage c, as shown in Fig. 9 of the drawings. By renewing` the lining e2 when worn, the feed-passage is maintained in proper condition without the necessity of renewing the entire plate E. After the before-described creasing and swaging process the bar from which the shoe is to be formed is advanced by the feed mechanism hereinafter described, which carries the creased and swaged portion of the bar in front of the oscillating former-arm K, the position of the bar being determined by a gage, r, which is adj ustably attached to the plate b, and adapted to be set a greater or less distance from the center of the portion of said plate traversed by the former M of the oscillatory arm K, ac` cording to the length of the bar required to form the shoe. The bar is carried to the gage r while the creasing and swag-ing mechanism are at rest, and in the next movement of said mechanism the bar is severed by two knives, ,fp p', one of which is attached to the inner end of the plate E, carried by the slide S, and the other knife, p', is attached to the plate b, hereinbefore described, said knives standing at right angles to the vfeed-passage a, and being caused to sever the iron by the approach of the slide S toward the creaser C in the operation of creasing and swaging the portion of the bar adjacent to that which is carried in front of the arm K. Ihe aforesaid knives I make adjustable in their position in relation to their distance from the gage r by fitting the plate E, which carries the knife p, loosely on the slide S, and providing said plate with a slot, s, through which its attaching-screw passes. Bylocsening said screw the plate E can be shifted tc carry the knife farther from or nearer to the gage or stop r, the 'knife being subsequently retained in position by tightening the attaching screw of the plate E. The other knife, p', is adjusted to conform to the IDO position of the knife p by interposing alin- By means of this lever I am enabled to draw the vswage rearward and away from its position over the feed-passage a, and thus prevent the swage from operating on the bar when desired, and also clear the passage of all obstructions, so that access ein be had thereto when required.

The4 former IWI and die L of the oscillating arm K are similar to those shown vin the patent of David L. Farmer and Samuel Farmer, hereinbefore referred to; but I now employ, in combination with the aforesaid parts, two jaws, N N, one on each side lof the die L. These jaws are connected with the formerarm K in such a manner as to allow them to yield endwise and laterally, and are normally held to f project at the face of the die L. The connection of said parts is here represented to consist in pivoting the lower port-ion of the jaws to the wide portion of the die L` with the face' of the hinged portion of the jaw Hush with the face of the die, the upper portion of the jaws being held in a protruding position by a spring, a, pressing against the inner end of thejaw, as illustrated in Fig. I4 ofthe drawings, the jaw having a lateral play on its pivotal pin.

On the outside of the jaws N N are plates IIO IIS

O O, hinged or pivoted, respectively, 'ro opposite sides of the arm K in such a manner as to allow the free ends of said plates to yield laterally. Suitable springs, a4, back of the plates near the heels thereof, as shown in Fig. 16 of the drawings, serve to hold the free ends of the plates o o to a certain degree normally `outward from the sides of the die Il.'

On the main shaft B is rigidly mounted a roller, W, arranged in position to be traversed by the free. end of the oscillatory arm K, and

- of a diameter to cause it to impinge the shoe held on the former M. Said roller is provided -with beveled projecting flanges or cheeksv v, which are fixed in such relative positions as to cause them to compress .the side plates, O Q, of the former-arm K.

`The operation of bending and completing the shoe after the blank has passed through the creasing and swaging process, as hereinbefore described, is as follows: In the descent of the arm K the protruding former encounters the center of the bar lying in the guidechannel a, and as the said former passes through the excision of the lower plate, b, theends of said excision press the bar around the former M, the jaws N N being in the meantime forced back from the face-of the former-arm bythe bearing of the edge of the upper plate, b', against the face of the said jaws. After the former-arm K has passed beneath the plate b the rollers 8 8 further bend the blank around the former, as hereinbefore described, and

thenlthe jaws N N automatically assume their normal projecting position, and thus embrace 'the sides of the shoe hanging on the former. The former-arm K next encounters the roller W, and in traversing the same the peripheral faceoflhe roller presses onto the face of the shoe, and at the same time the cheeks fv of the roller press the side plates, O O, ofthe arm Kagainst they sides of the jaws N N, and the latter against the sides of the shoe still adhering to the former M, thus compressing the shoe and subjecting it to a second swaging process, giving it an even contour and finishing the shoe.

The feed mechanism by which the heated bar is conveyed to the before-described shoeforming machine consists of two horizontal disks or rollers, It` R', mounted on vertical arbors 1, which are j ournaled in suitable boxes or bearings on a pedestal, 2,-said rolls being rotated synehronously,and in opposite directions by pinions 3.0i' equal dimensions fastened to the respective arbors. A miter-gear, 4, is attached to the end of the main shaft B and engages a miter-gear, 5, loosely mounted ou one of the arbors 1. A clutch, 6, slides on a feathered portion of the aforesaid arbor, and is adapted to interlock with the hub of the loosely-mounted miter-gear 5, which receives a continuous motion from the main shaft B. By means of a lever, 7, pivoted on the pedestal 2, and connected at one end with ythe clutch -6, and having the opposite end in a position to be conveniently manipulated by the operator,

the clutch can be thrown in and out of connection with the miter-gear 5, and thus the .feed-rolls Bf can be set in motion or stopped ,periphery of the upper portion of the rolls is mutilated, leaving only a segmental portion to grip the bar to be fed to the machine, the mutilated portion, losing its hold on the bar, produces an intermittent feed-motion, the intervals in the feed corresponding to the time required to crease and swage the portion of the bar entering into the machine. I do not, however, wish to be confined to the precise form or construction of the face of the feedrolls to .impart the intermittent movement to thebar from which theshoeis tobeformed,inas much as the feed-rolls may be arranged to receive an intermittent instead of a constant rotation.

Having described my invention, what I claim as new, and desire to secure by Letters Patent,
